Explain what happens to substances during a chemical change

In a chemical change, the atoms in the reactants rearrange themselves and bond together differently to form one or more new products with different characteristics than the reactants. When a new substance is formed, the change is called a chemical change.

A chemical change is when substances react chemically to make a product with a different identity than the reactants. The different identity is due to the rearrangement of the atoms in the reaction.
